The horse clearly has a preference for normal ground conditions. On standard racing surfaces, he wins roughly 2 out of every 5 races (2 wins from 5), a rate that stands out sharply against his overall record. When ground conditions are anything other than normal, his chances drop dramatically — this is the kind of detail that matters hugely if you want to back him. His first career win came at Leopardstown on 28 December 2024, and having now won twice more, he looks like a horse that has learned how to win.
Trainer Ross O'Sullivan, based at Kilcullen in County Kildare, has built a productive season with 40 winners sent out from the yard. Giant Haystacks has been ridden most often by Danny Gilligan, though that partnership has not yet produced a win from seven races together. The recent wins have come with different jockeys, which is worth noting — sometimes a change of rider can unlock something in a horse that was not quite working before. With a win this week and clearly some momentum building, Giant Haystacks looks like a horse that has turned a corner after years of modest returns.
